It appears that Turbo Tax does not allow someone born in 1949 to take a QCD. If you were born in 1949 you would turn 70.5 in 2020. If you make a QCD after you turned 70.5 in 2020 then you qualify for the deduction. However, Turbo Tax does not ask if some of the distribution was a QDC. If you change your birth year to 1948 then go back to the 1099 entry you are asked if part of the distribution was QDC. Then if you back and change you birth year to 1949 and leave your 1099 entry alone the QDC shows on the Form 1040.
This is an obvious error in the software and Turbo Tax should fix it!
